Ok...I know this is done because I see it all over the place. But I can't seem to find out what you need to do to preserve tree trunks/limbs for fence posts? Does anybody know what kind of preservative you need to apply?
I've never known anyone to put preseving on them,unless it's the store bought post.If you are talking about the plain looking ol'post,& I think you are.Then it depends on the type of wood it is.
For exp- pine would not last but afew years,Then locust will last for ever.Same as with some of the oaks.
